Internal current control structure The power MOSFET delivers a sense current I s which is proportional to the main current Id. R2 receives this current and the current coming from the FB pin. The voltage across R2 is then compared to a fixed reference voltage of about 0.23 V.

Turn on transient peak voltage, Vfp The voltage peak (overshoot) after instantaneous switching from zero or a specified reverse voltage to a specified
